Agentless Hardware Failure Detection via Firmware Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Information Handling Systems (IHS) face challenges in minimizing downtime and remote servicing due to the need for a functional Operating System (OS) and healthy hardware to communicate with remediation and recovery services, limiting their mobility and efficiency in remote remediation and recovery processes.
Innovation Solution
The implementation of agentless remediation and recovery techniques that allow an IHS to autonomously check and identify failed hardware components without involving the CPU or BIOS, using secure 'very low level communication' techniques, firmware-based iterative algorithms, and partial or full BIOS interaction to isolate and remediate failures, enabling remote servicing even in unserviceable areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional IHS relies on OS and healthy hardware to communicate with remediation services, then communication capability is maintained, but system availability and remote servicing capability are reduced when hardware fails or OS is unavailable
Solution Approach 1:
The patent segments the communication capability into multiple independent layers: a low-level firmware layer (below OS) that can communicate independently of hardware status, and the traditional OS layer. This segmentation allows remediation communication to persist even when OS or hardware fails, resolving the contradiction between reliability and complexity by distributing communication functions across layers rather than relying on a single complex OS-based architecture
Solution Approach 2:
The patent introduces a firmware-based intermediary layer that mediates between hardware and the remediation service. This firmware layer acts as a mediator that can detect hardware failures and communicate system state to remote services without requiring OS involvement, thereby maintaining reliability while avoiding the complexity of OS-dependent communication protocols
2Productivity
If IHS requires functional OS and healthy hardware for remediation communication, then communication reliability is maintained, but downtime is increased and mobility is reduced
Solution Approach 1:
The patent implements preliminary action by establishing a firmware-based communication capability that exists before OS initialization. This low-level firmware layer is configured to handle remediation communication independently, ensuring that communication availability is maintained even when OS is unavailable or hardware is failing, thereby reducing downtime without sacrificing reliability
Solution Approach 2:
The patent applies dynamics by making the communication architecture adaptive to system state. The firmware layer can dynamically adjust its communication behavior based on hardware health status, switching between different communication modes or protocols as needed, which enables continuous availability while maintaining reliability across varying system conditions
3Ease of operation
If agentless remediation uses firmware-based communication independent of CPU and OS, then remote servicing capability is improved, but system complexity at firmware level is increased
Solution Approach 1:
The patent extracts the remediation communication function from the OS and CPU-dependent architecture, placing it in a dedicated firmware layer that operates independently. This extraction simplifies the overall system operation for remote servicing while concentrating the complexity only in the firmware layer, which is designed specifically for this purpose and does not affect the main OS complexity
Solution Approach 2:
The firmware-based communication layer implements self-service capabilities by autonomously detecting hardware failures, determining system state, and communicating with remote remediation services without requiring OS or CPU intervention. This self-service approach improves ease of operation for remote servicing while keeping the firmware structure manageable through automation rather than manual complexity
4Loss of time
If hardware failure detection is performed without CPU or BIOS involvement, then response time is reduced, but detection complexity is shifted to lower levels
Solution Approach 1:
The patent applies preliminary action by pre-configuring firmware routines in the low-level communication layer that are specifically designed to detect hardware failures. These detection routines are established before OS initialization and can immediately detect failures without waiting for OS-level detection mechanisms, reducing detection time while managing complexity through pre-programmed detection logic
Solution Approach 2:
The patent replaces the traditional mechanical/CPU-based hardware detection mechanism with a firmware-based detection system operating at a lower level. This substitution enables faster detection by eliminating CPU involvement in the initial detection phase, while the complexity is managed through structured firmware routines rather than ad-hoc detection logic

AI summary
Systems and methods for agentless remediation and recovery. In an illustrative, non-limiting embodiment, an Information Handling System (IHS) may include a Central Processing Unit (CPU); a Basic Input/Output System (BIOS) coupled to the CPU; a logic controller coupled to the CPU; and a memory coupled to the logic controller, the memory having program instructions stored thereon that, upon execution by the logic controller, cause the IHS to: during a first stage, check an operational state of a plurality of hardware components within the IHS in the absence of any involvement by the CPU or the BIOS; and during a second stage following the first stage, identify a failed hardware component amongst the plurality of hardware components in the absence of any involvement by the CPU or the BIOS.
